Addition of aluminum chloride to the (η4-cyclohexadiene)Fe(CO)3 complex bearing an acid chloride side chain at C-5 gives a cyclic keto complex, whereas Lewis acid assisted intramolecular cyclization of acyclic (η4-butadiene)Fe(CO)3 complexes containing an aldehyde, an ester, or a nitrile functionality produces (σ,η3-allyl)tricarbonyliron complexes. Treatments of the (η4-butadiene)Fe(CO)3 complexes bearing a chromium carbene moiety in refluxing toluene lead to formation of furan derivatives by intramolecular addition of the diene ligand to the chromium carbene carbon center.
